Yes.
i think he does like 10 -------------------------------------------------------------------------------------------------------- No, it's actually not 10. It's 1600. Because Ralph likes perfect square roots. The ones he like: √25 = 5 √400 = 20 √144 = 12 The ones he doesn't like: √24 = 4.898979486... √300 = 17.32050808... √145 = 12.04159458... The answer choices: √10 = 3.16227766... √50 = 7.071067812... √124 = 11.13552873... √200 = 14.14213562... √1600 = 40 And also, he likes 400 and not 300, not vice versa.
It is 2 because 1800/2 = 900 which is a perfect square because 302 = 900
300*3 = 900 which is a perfect square because 30 squared equals 900
How about 150*6 = 900 which is a perfect square because 30*30 = 900
30 x 30 = 900
